Copying Specific lines of code from a .txt file and pasting them over lines in another .txt file


Recommended Posts

Hello Everyone,

I am very green when it comes to AutoIT, I have recently started using it to automate a job that i perform using MS Excel and that is working great. Recently I have been faced with a challenge I which i need to copy a specific set of lines from one .txt file and past them, overwriting a specific set of lines in a different .txt file. I honestly have no clue how I can copy the specified lines and transfer them. What functions / commands could I use and how could I lay them out I AutoIT? Any and all help will be appreciated. 

Thanks!

Depends how big are those text files.  If they are not too large, you could use _FileReadToArray to get the source and target files, then modify target array from source lines and copy back to target using _FileWriteFromArray.

As @Nine already pointed out, there are several possible approaches. It would be helpful, if you could post two sample texts (source, target). Then we would have an idea what you mean by 'specific set of lines'.

@Nine, @Musashi

Thank you guys for the quick replies! I attached the 2 files that are part of this process. what I am looking to do is open O8000.txt and copy lines 8-46 then Open O1800.txt and past the lines from O8000 and overwrite lines 22-29 in O1800. Thank you so much for the help guys, I really appreciate it!

O8000.txt O1800.txt

Since files are small, I would go with the array approach. Here something to start you up :

#include <File.au3>
#include <String.au3>

Opt ("MustDeclareVars", 1)

Local $aSource, $aTarget, $aExtract
_FileReadToArray ("O8000.txt",$aSource,$FRTA_NOCOUNT)
_ArrayDisplay ($aSource, "source file")
_FileReadToArray ("O1800.txt",$aTarget,$FRTA_NOCOUNT)
_ArrayDisplay ($aTarget, "before delete")
_ArrayDelete ($aTarget, "21-28")
_ArrayDisplay ($aTarget, "after delete")
$aExtract = _ArrayExtract ($aSource, 7, 45)
_ArrayDisplay ($aExtract,"extracted lines")
Local $sRange = StringTrimRight (_StringRepeat ("21;", UBound ($aExtract)),1)
_ArrayInsert ($aTarget, $sRange, $aExtract)
_ArrayDisplay ($aTarget,"new target")
_FileWriteFromArray ("O1800 New.txt", $aTarget)

@Kruxe : a little additional explanatory note :

_FileReadToArray (..., $FRTA_NOCOUNT) means : the arrays are 0-based ==> Line 1 therefore has the index 0 ! So don't get confused by the fact, that the "line numbers" are 1 smaller ;).

--> _ArrayExtract ($aSource, 7, 45) ==> your lines 8 - 46 in O8000.txt

--> _ArrayDelete ($aTarget, "21-28") ==> your lines 22 - 29 in O1800.txt

A pretty vague definition!

If I guess correctly you want to replace a tooling sequence by another one.  Does this do the job?

Local $sToBeCopied = StringRegExpReplace(FileRead("O8000.txt"), "(?s)(.*?\RN1.*?\R)(.*?\RM99\R)(.*)", "$2")
Local $sModified = StringRegExpReplace(FileRead("O1800.txt"), "(?s)(.*?\RN1.*?\R)(.*?\RM50\R(?=\h*\R))(.*)", "$1" & $sToBeCopied & "$3")
FileDelete("O1800_new.txt")
FileWrite("O1800_new.txt", $sModified)

      I have a autoit exe file which is used in upload/browse file functionality.  This has been integrated with selenium framework and I am invoking the autoit exe using Java process and runtime. 
      Now the issue is when I run the scripts and invoke the autoit exe in local it works perfectly.  But when I use selenium grid or jenkins to run the scripts in another windows server it is not working.
      Can anyone please suggest any solution for this?

      Hello, the script below will read column A from an excel file - and if a value matches in the browser, it will click the corresponding link and click on a specific button to paste the data, then writes "Completed" in Column B. It will continue to read from the excel file and do the same thing for all the remaining rows.

      What i am trying figure out now is if the excel crashes while the script/loop is running, I want to relaunch the excel file continue to the last row before the excel crashed. So if the value of column B is not marked as "completed", it should continue from that row
      Appreciate any help that I can get to achieve this.

      Hello ,
      I am trying to use Websockets in AutoIt.
      It is to fetch live stock market prices , API is provided and documentation available for python language.
      The link for the code snippet is :
      https://symphonyfintech.com/xts-market-data-front-end-api-v2/#tag/Introduction
      https://symphonyfintech.com/xts-market-data-front-end-api-v2/#tag/Instruments/paths/~1instruments~1subscription/post
       
      https://github.com/symphonyfintech/xts-pythonclient-api-sdk
       
      Second Link is to subscribe to a list of ExchangeInstruments.
      Now I would like to get live stock ltp (LastTradedPrice) for a few stocks whose "ExchangeInstrumentID" I know.
      I am able to use the WinHttp object to perform actions using simple codes like below :
      I have the secretKey and appkey and can generate the needed token. And get the unique ExchangeInstrumentID.

      Below code is just for example of how I am using WinHttp. Unrelated to socket part.
      Global $InteractiveAPItoken = IniRead(@ScriptDir & "\Config.ini", "token", "InteractiveAPItoken", "NA") $baseurl = "https://brokerlink.com/interactive/" $functionurl = "orders" $oHTTP = ObjCreate("winhttp.winhttprequest.5.1") $oHTTP.Open("POST", $baseurl & $functionurl, False) $oHTTP.SetRequestHeader("Content-Type", "application/json;charset=UTF-8") $oHTTP.SetRequestHeader("authorization", $InteractiveAPItoken) $pD = '{ "exchangeSegment": "NSEFO", "exchangeInstrumentID": ' & $exchangeInstrumentID & ', "productType": "' & $producttype & '", "orderType": "MARKET", "orderSide": "' & $orderside & '", "timeInForce": "DAY", "disclosedQuantity": 0, "orderQuantity": ' & $qty & ', "limitPrice": 0, "stopPrice": 0, "orderUniqueIdentifier": "' & $orderidentifier & '"}' $oHTTP.Send($pD) $oReceived = $oHTTP.ResponseText $oStatusCode = $oHTTP.Status
          
          
      But am struggling to understand and use socket.
      Would be of great help if you can have a look at the link mentioned above and help with the code sample for AutoIt.
      To connect and listen to a socket.
      Thanks a lot

      Hi, I have a site that has the following elements below: 
      <div>More element here</div> <div>More element here</div> <div>More element here</div> When I do this in Auto It:
      Local $oSelectDiv = _WD_FindElement($sSession, $_WD_LOCATOR_ByCSSSelector, "div") _WD_HighlightElement($sSession, $oSelectDiv, 1) I also tried to add [3], but it doesnt seems to work:
      Local $oSelectDiv = _WD_FindElement($sSession, $_WD_LOCATOR_ByCSSSelector, "div[3]") _WD_HighlightElement($sSession, $oSelectDiv, 1) It always highlight the first one, but I am trying to highlight the 3rd in the list. Is there anyway to select the 3rd div without having to add any class/id in the divs, and without using XPATH? The structure of the elements in that site were built that way.

      My au3 script program needs administrator privileges on win10 to be executed correctly, because it needs to be added to the boot---Script code:RegWrite("HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run", @ScriptName, "REG_SZ", @ScriptFullPath)
      I need to let the program automatically get administrator privileges, so I use a function of #RequireAdmin. Although the program can be added to the boot, but does not execute after system boot up? why is that?
      What should I do?
      --------------------------------------------------------------------
      Update:
      I found that after using the #RequireAdmin function, the program cannot be executed after system boot up.
      An example is given below. after it is compiled, it will not be executed after system boot up in the following two ways.
      1. C:\ProgramData\Microsoft\Windows\Start Menu\Programs\StartUp\
      2. RegWrite("HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run", @ScriptName, "REG_SZ", @ScriptFullPath)
      why is that?
      example
      #include <MsgBoxConstants.au3>
      #RequireAdmin
      Func test()
          MsgBox(0, "", "this is test message")
      EndFunc   ;==>test
      test()
